I build data pipelines and cloud warehouses that replace manual reporting, connect fragmented systems, and give teams data they can actually trust. My core work is GCP data engineering: BigQuery, Airflow, dbt, Python, SQL, ETL/ELT, API integrations, and data warehouse optimization. I also work across AWS, PostgreSQL, Redshift, and mixed legacy environments. I can help with: • AWS/GCP data infrastructure and cross-system integrations • ETL/ELT pipeline development and optimization • BigQuery data warehouse design, migration, and cost optimization • Airflow orchestration and production pipeline reliability • dbt transformations and analytics-ready data models • REST/API integrations and automated data ingestion • Legacy database and ETL migration to GCP • Python and SQL data engineering The technical work is only part of the job. I care about whether the pipeline is reliable, observable, maintainable, and actually useful to the people consuming the data. If you're dealing with unreliable pipelines, manual data work, slow reporting, expensive warehouse queries, or disconnected systems, send me the current setup and what you're trying to achieve. I'll give you a direct assessment of the best way to solve it.

I build data warehouses that run faster and cost less. One client went from a $4,000 monthly bill to $40, with query times dropping from 84 hours to 2. I help SaaS companies, agencies, and data-heavy startups move off slow, expensive setups and onto Snowflake, BigQuery, and dbt pipelines they can actually trust. WHAT I'VE SHIPPED ▸ Migrated 250 million records from PostgreSQL to Snowflake for a B2B data platform. Monthly cost fell from $4,000 to $40, query time from 84 hours to 2. ▸ Built the dbt and Snowflake pipeline behind an influencer dashboard serving Nike, Under Armour, and New Balance. Adding New Balance lifted annual revenue by $1.8M. ▸ Rebuilt the reporting layer for a coaching platform with 100,000 users, taking dashboard refresh from 6 hours down to near real time. ▸ Scraped 10,000+ restaurant outlets across DoorDash, Uber Eats, and Grubhub at a 98%+ success rate, feeding clean order data into BigQuery. WHAT I DELIVER ✔ ETL and ELT pipelines (Python, SQL) ✔ Cloud data warehouses (Snowflake, BigQuery, Redshift) ✔ Data migration and data modelling ✔ dbt transformations and Airflow orchestration ✔ Data ingestion (Fivetran, API integration) ✔ Web scraping and data extraction at scale ✔ Cloud infrastructure (GCP, AWS, S3, Lambda) ✔ Analytics and BI-ready datasets 150 contracts and $200K+ earned here, Top Rated Plus. Google Certified Professional Data Engineer, master's from Georgia Tech on a Fulbright scholarship, 8 years across these stacks. Based in Abu Dhabi, working US and EU hours, and I reply inside 4 hours. If your warehouse is slow or the bill keeps climbing, send me two things: what you're running now and roughly what you pay a month. I'll send back a free audit showing where the cost and the time are going, and what I'd change first. Let's talk in chat.

Your data pipeline is either driving decisions, or quietly slowing your business down. Most teams don’t struggle with data volume, they struggle with reliability. Pipelines fail without alerts, dashboards lag behind reality, and engineers spend more time fixing than building. The result is slower decisions, growing technical debt, and missed opportunities. I design and build robust, scalable data systems that simply work, from ingestion to analytics-ready data. The focus is always on clarity, performance, and reliability, so your team can trust the data and move faster without constant firefighting. My tech stack: Python, SQL, Spark, Apache NiFi, Airflow, Kafka, Flink, Snowflake, BigQuery, AWS, GCP, Docker, Terraform, and FastAPI. If you share your current setup or challenge, I’ll break down exactly how to fix or scale it. I usually respond within a few hours.

I build cloud-native data platforms at scale. Lakehouses, streaming systems, AI infrastructure. My clients are companies where bad data or downtime isn't an option. I have 6 years of experience designing and delivering greenfield data architectures for Fortune 100 enterprises across fintech, healthcare, and identity management. Most recently, I migrated a fintech platform off a single monolithic server onto a distributed lakehouse on AWS with Spark, Airflow, and Apache Iceberg. That cut pipeline runtimes by 50% and infrastructure costs by 40%. Here's what I work with: Lakehouse & batch: Spark, PySpark, Databricks, Iceberg, Hudi, Trino, Airflow Streaming & CDC: Kafka, Debezium, ksqlDB, Spark Structured Streaming, ClickHouse Cloud: AWS (EKS, EMR, Glue, Lambda, SageMaker), Azure (AKS, Databricks, AI Foundry) Infrastructure: Kubernetes, Terraform, Helm, Docker, GitHub Actions CI/CD Governance: Apache Ranger, RBAC, row-level security, HIPAA/GDPR/SOC 2 AI/ML infra: RAG pipelines, vector databases (Pinecone), LLM-backed applications I've contributed to open-source projects like Debezium (Red Hat's CDC platform) and Mage.ai. I work independently, communicate proactively, and I'm used to collaborating remotely across US, EU, and Middle East time zones. If you need someone who can own the architecture end to end, not just write pipelines, let's talk.

Hadoop Developers Hiring FAQs

What is a Hadoop developer?

Hadoop developers are responsible for developing and coding applications in the Hadoop open-source framework, which is primarily focused on handling big data for companies.

How do you hire a Hadoop developer?

You can source Hadoop developer talent on Upwork by following these three steps:

  1. Write a project description. You’ll want to determine your scope of work and the skills and requirements you are looking for in a Hadoop developer.
  2. Post it on Upwork. Once you’ve written a project description, post it to Upwork. Simply follow the prompts to help you input the information you collected to scope out your project.
  3. Shortlist and interview Hadoop developers. Once the proposals start coming in, create a shortlist of the professionals you want to interview. 

Of these three steps, your project description is where you will determine your scope of work and the specific type of Hadoop developer you need to complete your project. 

How much does it cost to hire a Hadoop developer?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.
